Analysis on the coupling characteristics of urban ecological structure and local economy in the Yellow River Basin

The Yellow River Basin is an important part of China's ecological protection areas, but the stable development of the Yellow River Basin cannot be guaranteed due to the unreasonable setting of the local ecological structure and the slow pace of economic development. Many scholars at home and abroad have researched the ecological structure and urbanization level of the Yellow River Basin, but there is still a lack of work to analyze the coupling characteristics of the two. In this paper, the entropy weight method is used to study the coupling characteristics of economic development and ecological structure in the Yellow River Basin. The ecological environment, urbanization evaluation system and the ecological environment and urbanization coupling coordination characteristic evaluation system are constructed. The results show that the comprehensive evaluation coefficient of urbanization has increased by 276.2% from 2011 to 2020. The annual average increase of the comprehensive evaluation index of the ecological environment is over 35%. The degree of matching between the level of urban modernization and the ecological environment is basically above 95%.
